Application inea January 19, 1914. serial No. 813,081.

T0 all whom t may concern: v

` Be it known that I, PIERRE LONARD Lnrssn, citizen of the French Republic, residing at Billancourt, Department of the Seine, in France, have invented certain new and useful ImprovementsRelating to Lubrication of Motors; and I do hereby decla-re the following to be a full, clear, and exact description of the invention, suchas will enable others'skilled in the art to which it appertains to make and use the same.

This invention relates to lubricating systems for motors, and especially to systems intended to insure good lubrication of the crank pins and the connecting rod head bearings.

The object of the invention is to provide meansespecially adapted for use in connection with splash lubricating systems to insure the supply off a quantity of lubricant to the connecting'rod vhead bearings. This is preferably accomplished by collecting a portion -of the lubricant splashed in the crank case of the motor on disks secured to the side walls of the crank arms, the disks being provided atv their peripheries with circular grooves which collect the lubricant thrown outwardly by centrifugal force.

From the circular grooves, the lubricant is conducted to the surface of the crank pins to lubricate the connecting rod head'bearings by suitably formed conduits. Thisarrangement of parts is simple in its construction and may be readily assembled and insures an excellent lubrication of the parts in a motor, in which the splash lubricating sysv tem is employed.

tional view taken Fig. 1.

. The invention is illustrated in the accompanving drawing, in which Figure 1 is a sectional view of av crank shaft with the improved lubricating means applied thereto: and Fig. 2 is a broken secon the line -A--A of In Fig. 1, two adjacent crank pins' are' shown, to which the connecting rod heads may be connected in the usual manner. The crank pins 1 and 2V are connected by the crank arm 3 of the crank shaft.l Circular disks 4, provided attheir peripheries with grooves 5, are securedV to opposite sides of the crank arm 3. A small tube'7, engaging in a recess 7 of the crank arm, places each groove 5 in communication with the outer 'surface of one of the crank pins through the intermediary of an inclined conduit 8.

with recesses 6 conforming in shape to the contour of the crank pins, so that when the disks are positioned. each recess in the disk will accommodate the adjacent crank pin, as clearly shown in Fig. 1.

The operation of the construction isas follows: During the operation of the motor, the lubricant splashed inside of the crank case is collected on the disks 4, and it is then thrown by centrifugal force to the peripheral grooves 5, where it is collected and conducted, by means of the inclined conduits 8, to the surfaces of the crank pins. The lubrication of the connecting rod head bearings, is, therefore, insured. The disks, if so desired. may be mounted. in eccentric relation with respect to the axis of the crank.

conduit 8 will communicate with the groove 5 at the extremity of the longest radius of the disk. Under these conditions, the greater part of the lubricant will collect in that portion of the groove adjacent the conduit 8.

Obviously. numerous changes mav be ma de in the details of construction without departing from the spirit or scope of the invention, as defined in the accompanying claims.

In a motor haying a crank shaft, a lubricant-collecting disk secured to the side of the crank arm and disposed in eccentric re' lation with the axis of the crank shaft, and a conduit adapted to conduct the lubricant collected on said disk to one of the adjav cent crankV pins, said conduit communicating with the disk at the extremity of the greatest radius of the disk- 2.
